All-Climate Battery (ACBTM)

A breakthrough technology delivers 10X power and 15-min fast charging in cold environments as low as -30oC

All-Climate Battery for Unprecedented Low Temperature Performance

 Insertion of a new material followed by new cell design exploits self heating of cell.

For more details, see our publication in 








Large Batch Production of All-Climate Battery Cells


We fabricated thousands of prismatic and pouch cell in 10 to 20 Ah capacity to demonstrate viability for mass production and in-vehicle testing.







Technology Progression

For ACB cells to enjoy a dramatic power boost at low temperatures, some activation time and energy (or charge) consumption are required. Currently <15 sec and <3% of cell energy is consumed during activation. 





World's First Fast Rechargeable Battery at Low Temperature


We have demonstrated >10X fast charging of ACB cells compared to state-of-the-art Li-ion cells at -30oC without sacrificing life.
